zcebe Co-Supervisor: Assoc. Prof. Dr. BariS Binici May 2009, 162 pages FRP retrofitting allows the utilization of brick infill walls as lateral load resisting elements. This practical retrofit scheme is a strong alternative to strengthen low to mid-rise deficient reinforced concrete (RC) structures in Turkey. The advantages of the FRP applications, to name a few, are the speed of construction and elimination of the need for building evacuation during construction. In this retrofit scheme, infill walls are adopted to the existing frame system by using FRP tension ties anchored the boundary frame using FRP dowels. Results of experiments have previously shown that FRP strengthened infill walls can enhance lateral load carrying capacity and reduce damage by limiting interstory drift deformations. In previous, analytical studies, a detailed mathematical model and a simplified version of the model for compression struts and tension ties was proposed and verified by comparing model estimations with test results. In this study, an existing 9-storey deficient RC building located in Antakya was chosen to design and apply a hybrid strengthening scheme with FRPs and reduced number of shear walls. Linear elastic analysis procedure was utilized (force based assessment technique) along with the rules of Mode Superposition Method for the reftrofit design. FRP retrofit scheme was employed using the simplified model and design was conducted such that life safety performance criterion is satisfied employing elastic spectrum with 10% probability of exceedance in 50 years according to the Turkish Earthquake Code 2007. Further analytical studies are performed by using Modal Pushover and Nonlinear Time-History Analyses. At the end of these nonlinear analyses, performance check is performed according to Turkish Earthquake Code 2007, using the strains resulting from the sum of yield and plastic rotations at demand in the critical sections. CFRP retrofitting works started at October 2008 and finished at December 2008 for the building mentioned in this study. Eccentric reinforced concrete shearwall installation is still being undertaken. All construction business is carried out without evacuation of the building occupants. This project is one of the first examples of its kind in Turkey.

Повний текст джерелаSyfte: I Sverige råder det brist på bostäder, skolor och förskolor, samtidigt uppmäter koldioxidutsläppen högre än någonsin och insikten om ett miljöhot är påtaglig. Byggnadssektorn ansvarar för en stor del av Sveriges koldioxidutsläpp. Beräkning av klimatpåverkan kan utföras genom livscykelanalyser (LCA), däremot efterfrågas direktiv på vad som bör göras vid byggnation kring ett LCA-perspektiv. Undersökningen har genomförts på en modulbyggnad som utgör ett effektivt och flexibelt sätt att hantera byggnadsbristen på. Målet med arbetet var att ur ett ekologiskt hållbart perspektiv få svar på vad som är mer fördelaktigt att behandla moduler på när det tidsbegränsade bygglovet löpt ut och en modul behövs på en annan plats, med eller utan en tilläggsisolering. Metod: För att uppnå målet med studien användes en kvantitativ undersökningsstrategi. Klimatpåverkan för fyra olika typer av livscykler simulerades i mjukvaruprogrammet Anavitor. Andra metoder som används för datainsamling var dokumentanalys, beräkningar av specifik energianvändning och transmissionsförluster genom vägg vid tilläggsisolering. Resultat: Det genererade resultatet presenterar vad som är fördelaktigt att välja efter att det tidsbegränsade bygglovet löpt ut och en ny modul behövs på en annan plats. Studien visar att det genererar mycket mindre koldioxidutsläpp att återanvända modulen än att kassera och bygga ny modul. En energibesparing kan ges som sänker den totala klimatpåverkan för modulerna som tilläggsisoleras. Konsekvenser: Slutsatsen av arbetet är att produktions och tillverkningsstadiet har så pass stor inverkan på den totala klimatpåverkan då utfallet att renovera och spara in på en tillverkningsfas är att föredra. För att göra valet av att tilläggsisolera eller inte krävs en LCA. Den koldioxidökningen som tillkommer på grund av volymökning av en tilläggsisolering får inte överskrida den minskning som genereras av energibesparing. Begränsningar: Studien är avgränsat till livscykelanalys gjord på modulens klimatskal då den invändiga och tekniska utrustningen är densamma för alla utfall, därför kan modulen även tillhöra en annan slags funktion. Resultatet blev till en början specifikt men med hjälp av beräkning av brytpunkt för oberoende transportsträckor kunde en generell giltighet ges.

Повний текст джерелаENGLISH ABSTRACT: The construction industry is a competitive market and contractors need to keep up-to-date with new construction methods and technologies. Project teams in South Africa are required to make decisions during the early stages of construction projects. These decisions often need to be made in a short time period, and include the decision between various construction methods, such as the decision between in-situ concrete construction and hybrid concrete construction. Hybrid concrete construction is a combination of pre-fabricated concrete and cast in-situ concrete to obtain the supreme benefits of their different construction qualities. This method of construction is ultimately used to achieve faster, and occasionally, more cost effective construction. Hybrid concrete construction, today, is a well-known term in the construction industry and is widely used in the UK and other developed countries. However, the use thereof is limited in South Africa, and in-situ concrete construction remains the conventional method of construction. Possible reasons for the limited use of hybrid concrete construction are investigated in this study. With the intent of improving the construction industry of South Africa, guidelines are provided to assist project teams in a decision between in-situ concrete construction and hybrid concrete construction. The decision between construction methods is based on many factors, such as project time, cost, quality, safety, environmental performance, socio-economic aspects (labour) and client satisfaction. Project time and cost are, however, the most important of these factors. It is stated that the structure of a building represents typically only 10 % of the construction cost, however, the choice of construction method and material can have significant effects on the cost of other elements throughout the life cycle of construction projects. It is therefore important to measure the whole life cycle cost when deciding between construction methods, such as in-situ concrete construction and hybrid concrete construction. The aim of this study is to identify and investigate the factors that influence project time and cost, throughout the life cycle of construction projects, and to provide a framework that can assist project teams in their decision between in-situ concrete construction and hybrid concrete construction in South Africa. The decision between these two construction methods is influenced by a vast number of variables that may be difficult to quantify. The framework therefore consists of qualitative information that can assist project teams in their decision. The framework provided in this study includes the factors that have an influence on the time and cost for a decision between in-situ concrete construction and hybrid concrete construction. These factors are identified for the three primary phases in the life cycle of construction projects. These phases are the design phase, the construction phase and the maintenance phase.
AFRIKAANSE OPSOMMING: Die konstruksiebedryf is 'n kompiterende mark en kontrakteurs moet op datum bly met nuwe konstruksie metodes en tegnologieë. In Suid-Afrika word daar van projek spanne vereis om vinnige besluite gedurende vroeë stadiums van 'n projek te neem. Hierdie besluite moet dikwels in 'n kort tydperk geneem word, en sluit die besluit tussen verskillende konstruksie metodes in, byvoorbeeld die besluit tussen in-situ en hibriede beton konstruksie. Hibriede beton konstruksie (HBK) is 'n kombinasie van in-situ en voorafvervaardigde beton elemente. HBK word in die algemeen gebruik om te baat uit 'n vinniger konstruksie tydperk, en kan soms ook ‘n meer koste-effektiewe metode van konstruksie wees. HBK word gesien as 'n bekende term in die konstruksiebedryf en word veral toegepas in ontwikkelde lande soos die VSA, Japan en Engeland. Die toepassing daarvan in Suid-Afrika is egter beperk. In Suid-Afrika word in-situ beton konstruksie nog steeds die meeste gebruik en staan dus bekend as die mees algemene metode van konstruksie. Hierdie studie ondersoek moontlike redes vir die beperkte gebruik van HBK in Suid-Afrika. Met die oog op 'n verbeterde konstruksiebedryf in Suid-Afrika, word rigylyne voorsien, wat projek spanne kan gebruik vir 'n besluit tussen in-situ en hibriede beton konstruksie. Daar is verskeie faktore wat 'n rol speel in die besluit tussen twee konstruksie metodes. Hierdie faktore sluit in, die tyd, koste, kwaliteit, veilighed, omgewings impak, sosio-ekonomiese aspekte (soos arbeid) en kliënt tevredenheid, van 'n projek. Tyd en koste is egter die belangrikste van hierdie faktore. Die metode waarvolgens 'n struktuur gebou word kan 'n beduidende uitwerking op die koste van ander elemente in die lewensiklus van 'n konstruksie projek hê. Dit is gevolglik belangrik om die hele lewensiklus koste in ag te neem wanneer daar besluit moet word tussen verskeie konstruksie metodes, soos in-situ en hibriede beton konstruksie. Die doel van hierdie studie is gevolglik om die faktore wat 'n invloed het op die tyd en lewensiklus koste van konstruksie projekte te identifiesieer. Hierdie faktore word dan gebruik om 'n raamwerk voor te stel. Projek spanne kan hierdie raamwerk gebruik as 'n riglyn om te besluit tussen in-situ en hibriede beton konstruksie. Die besluit tussen hierdie twee konstruksie metodes is afhanklik van 'n groot aantal veranderlikes, wat moeilik is om te kwantifiseer. Die raamwerk bestaan dus uit kwalitatiewe inligting wat projek spanne kan gebruik om 'n ingeligte besluit te neem oor in-situ en hibriede beton konstruksie. Die raamwerk wat in hierdie studie voorgestel word sluit dus die faktore in wat 'n invloed het op die tyd en koste vir 'n besluit tussen in-situ en hibriede beton konstruksie. Hierdie faktore is geïdentifiseer vir die drie primêre fases in die lewensiklus van 'n konstruksie projek. Hierdie fases is die ontwerp fase, die konstruksie fase en die onderhoud fase.

Повний текст джерелаPrefabrication of wood wall elements in construction of villas and terraced houses is a building method undergoing growth in recent decades. Cost efficiency is often cited as a reason why prefabrication has undergone such a large growth. At the same time, the issue of environmental impact and climate change has grown. As the construction sector accounts for a large part of Sweden's carbon dioxide emissions, the construction sector needs to become more sustainable. This thesis has examined this cost-effectiveness and if it is possible to combine with environmental sustainability. To examine this more thoroughly a comparison is made with in site-built timber-framed constructed walls. The thesis has been conducted in collaboration with Skidstahus, which produces prefabricated wall elements in a factory environment, especially for data collection. Information and data have also been collected from Varbergshus / Derome producing houses in site-built timber-framed building. A cost comparison of the building methods shows that the prefabricated wall elements manufactured by Skidstahus are more cost-effective, which can be linked to work efficiency. To some extent, the thesis also shows that material use can be optimized at Skidstahus production and therefore results in less waste, which thus reduces environmental impact. Other important factors for durability and accounted life span is the building method’s ability to handle migration of moisture and airtightness. The thesis shows that prefabricated walls have challenges, as joints and connections must be well designed. At the same time, factory production allows an environment which can reduce risk of migration of moisture as it provides protection for climate and weather impact. Another aspect is that it provides a good and well-tempered work environment for the construction worker. On the other hand, it is questionable whether the use of prefabricated wall elements affects the environment as it may increase the need of transportation in relation to on site-built timber-framed walls, as transport to and from the factory is required. In addition, the prefabricated method could influence how design and architecture is carried out while a wood house made from stick timber is more easily modified. In summary, the analysis show that the use of prefabricated wood wall elements reduces building costs while at the same time it can contribute to environmental sustainability. However, further studies are required to compare the estimated life span of the two compared building methods.

Do the house forms and residential neighborhoods commonly found in the U.S. accommodate the present needs and lifestyles of the people who live in them? The single-family detached house and multi-family units like the triple-decker originated in an era quite unlike the one in which we now find ourselves. I intend to explore the possibility that we may not have to adapt to a dwelling sensibility that is restrictive and inappropriate for the late 20th and early 21st centuries. Perhaps the result will not look radically different than the models we already know but will only function in a subtly different manner, for very specific reasons of use and daily life. I will design a piece of a residential neighborhood in Newton Upper Falls, Massachusetts based on the premise that the physical, organizational, and functional aspects of housing design do affect and can contribute to the quality of people's lives. Some questions that I find valid for exploration in the context of housing are: 1) can a mix of uses animate a neighborhood by providing commonly needed services and by reducing the isolation of the home from everything else in life: work, shopping, child care, entertainment?; 2) have we been perpetuating outdated Victorian ideals about the separation of work and home based on roles related to gender? If so, couldn't housing design be more progressive in supporting the way women and men actually live today rather than the way one's great-grandparents lived?;
(cont.) 3) if women still perform most of the household chores and child-rearing in the U.S. (whether married, single, or divorced), with the majority of American women also working full-time and getting paid two-thirds the salary of men, couldn't there exist a type of housing that considers the enormous demands on a person's time, energy, and resources necessary to accomplish all of this? I intend to research selected examples of feminist and experimental housing designs prior to starting my own. The Danish precedent of cohousing and Dolores Hayden's historical research and interpretive stance will establish my basic approach to the design project and its program. The design will be further informed by my own rethinking of domestic life and the architectural implications of it, recorded in "patterns" similar in intention to those of Alexander, et al.

Повний текст джерелаA gestão de edifícios ao longo do seu ciclo de vida é atualmente um problema que requer uma grande otimização, considerando o alto custo associado à utilização dos edifícios e devido aos custos de operação e manutenção. O número de edifícios existentes que necessitam de ações de reabilitação justifica a necessidade de um modelo de intervenção que otimize a sua vida útil após o processo de reabilitação. O custo do ciclo de vida é uma técnica usada para analisar vantagens de diferentes propostas, relacionadas com o planeamento do ciclo de vida do edificio, que avalia todos os custos que envolvem um ativo durante toda a sua vida, nomeadamente o custo de investimento, operação, manutenção e de fim de vida. No que diz respeito à otimização da gestão do ciclo de vida do edificio, propõe-se a metodologia BIM, que combina o Building Life Cycle Management (BLCM) e a informação digital tendo como suporte o modelo 3D, permitindo mais rigor e controle do que os processos manuais, contribuindo para a redução de perda de informação durante o ciclo de vida do edificio, e facilitando a comunicação entre os vários intervenientes. Assim, a presente dissertação tem o objetivo de otimizar a gestão do ciclo de vida de edifícios e minimizar os custos ao longo deste processo. Para atingir os objetivos pretendidos é analisada a aplicação do BLCM a um caso de estudo de um edifício em reabilitação, no qual se avalia a vida útil das soluções de reabilitação, usando o método fatorial apresentado na ISO 15686. Foi assim possível avaliar quais são as melhores soluções de reabilitação, em termos de durabilidade, comparando com diferentes propostas, e calcular o custo do ciclo de vida. Analisa ainda, a aplicação da metodologia BIM ao caso de estudo, concluindo-se sobre a respetiva vantagem na determinação do Custo do Ciclo de Vida e para o planeamento das ações de manutenção do edifício.
Buildings management along with its life cycle is currently an issue that requires a great optimisation considering the high cost associated with the buildings use and due to the operation and maintenance costs. The number of existing buildings needing rehabilitation actions justify the need of an intervention model that optimise its service life after the rehabilitation process. The Life Cycle Cost is a technique used to analyse the advantages of different proposals related to the planning of the building life cycle and to avaluate all costs involving an assets throughout its life, including investiment, operation maintenance and end of life. Regarding otimizing the Building Life Cycle Management it is proposed BIM methodology that is a combination of Building Life Cycle Management (BLCM) and the digital information of 3D modeling that allows more reability and control than manual process. BLCM also contributes for the reduction of information loss during the building life cycle, and facilitates communication between the stakeholders. So, this thesis aims to optimize the Building Life Cycle Management and minimize costs throughtout this process. In order to achieve the desired objectives, this dissertation analyses the application of BLCM to a case study under a rehabilitation process. With this, it was possible to assess if the solutions of rehabilitation are the best in terms of durability, when compared with other proposals and it allows to calculate the Life Cycle Cost. It was analysed and concluded that the application of BIM methodology can bring advantages for Life Cycle Cost and for future maintenance of buildings.
Djuric, Natasa. "Real-time supervision of building HVAC system performance." Doctoral thesis, Norwegian University of Science and Technology, Faculty of Engineering Science and Technology, 2008. http://urn.kb.se/resolve?urn=urn:nbn:no:ntnu:diva-2215.
Повний текст джерелаThis thesis presents techniques for improving building HVAC system performance in existing buildings generated using simulation-based tools and real data. Therefore, one of the aims has been to research the needs and possibilities to assess and improve building HVAC system performance. In addition, this thesis aims at an advanced utilization of building energy management system (BEMS) and the provision of useful information to building operators using simulation tools.
Buildings are becoming more complex systems with many elements, while BEMS provide many data about the building systems. There are, however, many faults and issues in building performance, but there are legislative and cost-benefit forces induced by energy savings. Therefore, both BEMS and the computer-based tools have to be utilized more efficiently to improve building performance.
The thesis consists of four main parts that can be read separately. The first part explains the term commissioning and the commissioning tool work principal based on literature reviews. The second part presents practical experiences and issues introduced through the work on this study. The third part deals with the computer-based tools application in design and operation. This part is divided into two chapters. The first deals with improvement in the design, and the second deals with the improvement in the control strategies. The last part of the thesis gives several rules for fault diagnosis developed using simulation tools. In addition, this part aims at the practical explanation of the faults in the building HVAC systems.
The practical background for the thesis was obtained though two surveys. The first survey was carried out with the aim to find the commissioning targets in Norwegian building facilities. In that way, an overview of the most typical buildings, HVAC equipment, and their related problems was obtained. An on-site survey was carried out on an example building, which was beneficial for introducing the building maintenance structure and the real hydronic heating system faults.
Coupled simulation and optimization programs (EnergyPlus and GenOpt) were utilized for improving the building performances. These tools were used for improving the design and the control strategies in the HVAC systems. Buildings with a hydronic heating system were analyzed for the purpose of improving the design. Since there are issues in using the optimization tool, GenOpt, a few procedures for different practical problems have been suggested. The optimization results show that the choice of the optimization functions influences significantly the design parameters for the hydronic heating system.
Since building construction and equipment characteristics are changing over time, there is a need to find new control strategies which can meet the actual building demand. This problem has been also elaborated on by using EnergyPlus and GenOpt. The control strategies in two different HVAC systems were analyzed, including the hydronic heating system and the ventilation system with the recovery wheel. The developed approach for the strategy optimization includes: involving the optimization variables and the objective function and developing information flow for handling the optimization process.
The real data obtained from BEMS and the additional measurements have been utilized to explain faults in the hydronic heating system. To couple real data and the simple heat balance model, the procedure for the model calibration by use of an optimization algorithm has been developed. Using this model, three operating faults in the hydronic heating system have been elaborated.
Using the simulation tools EnergyPlus and TRNSYS, several fault detection and diagnosis (FDD) rules have been generated. The FDD rules were established in three steps: testing different faults, calculating the performance indices (PI), and classifying the observed PIs. These rules have been established for the air cooling system and the hydronic heating system. The rules can diagnose the control and the component faults. Finally, analyzing the causes and the effects of the tested faults, useful information for the building maintenance has been descriptively explained.
The most important conclusions are related to a practical connection of the real data and simulation-based tools. For a complete understanding of system faults, it is necessary to provide real-life information. Even though BEMS provides many building data, it was proven that BEMS is not completely utilized. Therefore, the control strategies can always be improved and tuned to the actual building demands using the simulation and optimization tools. It was proven that many different FDD rules for HVAC systems can be generated using the simulation tools. Therefore, these FDD rules can be used as manual instructions for the building operators or as a framework for the automated FDD algorithms.
Denne avhandlingen presenterer noen fremgangsmåter for forbedring av ytelser for VVS-tekniske anlegg i eksisterende bygninger basert på bruk av simuleringsverktøy og virkelige måledata. Ett av målene har vært å undersøke behov og muligheter for vurdering og forbedring av ytelser for VVS-anlegg i bygninger. I tillegg har denne avhandlingen hatt som mål å fremme bruk av SD-anlegg samt å fremskaffe nyttig informasjon til driftspersonalet.
Bygninger blir stadig mer kompliserte systemer som inneholder flere og flere komponenter mens SD-anlegg håndterer en stadig større mengde data fra bygningsinstallasjoner. På den ene siden registreres det ofte feil og problemer med hensyn til ytelsene til de VVS-tekniske installasjonene. På den andre siden innføres det stadig strengere lovmessige pålegg og kost-nyttekrav motivert i energieffektiviseringen. SD-anlegg og databaserte verktøy bør derfor brukes mer effektivt for forbedring av ytelsene.
Avhandlingen består av fire hoveddeler hvor hver del kan leses separat. Den første delen, som er basert på literatturstudie, forklarer funksjonskontroll som begrep og prinsipper for oppbygging av verktøy for funksjonskontroll. Den andre delen presenterer praktisk erfaring og problemstillinger utviklet og behandlet i løpet av arbeidet med avhandlingen. Den tredje delen handler om anvendelse av databaserte verktøy for forbedring av ytelsen for VVS-tekniske installasjoner. Den tredje delen er delt opp i to kapitler, hvorav et handler om forbedring av systemløsninger og et om forbedring av styringsstrategier. Den siste delen presenterer flere regler for feilsøking og diagnostisering utviklet gjennom bruk av simuleringsverktøy. I tillegg gir denne delen en praktisk forklaring av feilene i de VVS-anleggene som er behandlet i undersøkelsen.
Det praktiske grunnlaget for avhandlingen er etablert gjennom to undersøkelser. Den første var en spørreundersøkelse som hadde til hensikt å kartlegge målsetninger for funksjonskontroll i norske bygninger. Gjennom dette ble det etablert en oversikt over de mest typiske bygninger med tilhørende VVS-anlegg og de mest forekommende problemene. En dypere undersøkelse ble utført på ett casebygg. Denne undersøkelsen viste seg å være nyttig både for kartlegging av betydningen av organisering av driften av bygningen og for avdekking av de virkelige feilene i det vannbårne oppvarmingssystemet.
En kobling mellom et simulerings- og et optimaliseringsprogram (EnergyPlus og GenOpt) har vært benyttet for forbedring av ytelsene for de VVS-tekniske installasjonene. Disse verktøyene har vært brukt for forbedring av både systemløsningene og styringsstrategiene for VVS-anlegg. Bygninger med vannbåren oppvarmingssystem har vært analysert for å forbedre systemløsningen. På grunn av begrensninger i bruken av optimaliseringsverktøyet GenOpt, har det blitt utviklet egne prosedyrer for håndtering av visse typer problemstillinger hvor denne begrensningen opptrer. Resultatene for optimaliseringen viser at valg av objektfunksjoner påvirker betydelig parametrene i det vannbårne oppvarmingssystemet.
Endringer i egenskapene til både bygningskonstruksjoner og utstyr som skjer på grunn av aldring over tiden, gjør det nødvendig med tilpassning av styringsstrategier slik at det virkelige behovet kan bli dekket. Denne problemstillingen har vært analysert ved bruk av EnergyPlus og GenOpt. Styringsstrategiene for to forskjellige VVS-anlegg, et vannbåret oppvarmingssystem og et ventilasjonsanlegg med varmegjenvinner har blitt behandlet. Den utviklete prosedyren for optimalisering av styringsstrategien består av følgende steg: innføring av optimaliseringsvariabler og objektfunksjon, samt utvikling av informasjonsflyt for behandling av optimaliseringsprosessen.
De virkelige data, både fra SD-anlegg og tilleggsmålinger, har vært benyttet for praktisk forklaring av feilene i oppvarmingssystemet. En prosedyre for modellkalibrering basert på bruk av en optimaliseringsalgoritme som kobler sammen de virkelige data og en enkel varmebalansemodell har blitt foreslått. Tre konkrete driftsfeil i oppvarmingssystemet har blitt belyst gjennom bruk av denne varmebalansemodellen.
Flere regler for feilsøking og diagnostisering har blitt utviklet ved hjelp av simuleringsverktøyene EnergyPlus and TRNSYS. Denne utviklingen har bestått av tre ulike steg: testing av bestemte feil, beregning av ytelsesindikatorer og til slutt klassifisering av de observerte ytelsesindikatorer. Reglene har blitt utviklet for et system av aggregater for luftkjøling og for et vannbåret oppvarmingssystem. Reglene kan diagnostisere både styringsfeil og komponentfeil. Til slutt presenteres informasjon som er nyttig for drift av VVS-tekniske installasjoner i bygninger basert på en analyse av årsakene for og virkningene av de feil som er behandlet.
De viktigste konklusjonene er knyttet til praktisk kombinasjon av virkelige måleverdier og simuleringsverktøy. Informasjon fra det virkelig liv er helt nødvendig for å få en god forståelse av feil som oppstår i anlegg. Det er også vist at potensialet som ligger i alle de data som er tilgjengelige gjennom SD-anlegg, ikke er fullt utnyttet. Gjennom bruk av simuleringsverktøy kan styringsstrategiene alltid bli bedre tilpasset og innjustert til de virkelige behov i bygningen. Simuleringsverktøy kan også brukes for utvikling av prosedyrer for feilsøking og diagnostisering i VVS-tekniske anlegg. Disse prosedyrene kan brukes enten som en veileder for manuell feilsøking og detektering eller som grunnlag for utvikling av automatiserte algoritmer.

Повний текст джерелаThis study explored communication and ethical investment in social capital to improve quality of life through the lens of time banking, a model of alternative currency. Previous studies of time banking noted a distinct set of characteristics of time banks that contrast with capitalist-based systems while using similar language; these were compared to research of social capital and social networks. Seven participants were interviewed at-length as representatives of the time bank movement. Stories of money framed theoretical constructs in practice on a daily basis and future visioning of the movement. Further analysis using the dialogic ethic of Martin Buber and the theory of the coordinated management of meaning (CMM) of Pearce and Pearce described transformational patterns of communication in time banks. The analysis shed light on the intentions of time banks and the meaning of the terms reciprocity, community and co-construction of reality. Further explorations of transcendent stories of time banking were recommended.

Повний текст джерелаDen här rapporten täcker skapandet av en metod för dynamisk eldspridning i en realtidsmiljö. Syftet är att se om det är möjligt att skapa ett system som kan kontrollera spridningsbeteendet och den visuella designen av elden baserat på någon sorts simplifierad parametrisering, Syftet härstammar ifrån att det saknas system där man kan kontrollera och designa ett eldspridningsscenario. För att nå resultat så skapas en metod som är baserad på syftet att använda ett parameterbaserat system, denna metoden skapas med hjälp av programmering i en realtidsmotor genom att kontrollera det visuella samt beteendet hos inbyggda partikelsystem. Resultatet visar eldspridning genom ett exempelscenario där elden beter sig olika baserat på vilket material som brinner, baserat på parametrar som är satta av en artist. Slutsatsen av resultatet visar att det är möjligt att skapa ett parameterbaserat eldspridningssystem och att det kan användas för att kontrollera den visuella designen och beteende samt att det kan expanderas för att förse artister med bättre kontroll över systemet. Rapporten föreslår fortsatta studier inom området simplifierade kontrollerade eldsimulationer inom realtidsmotorer, och användarvänlighet.

Life cycle assessment, or LCA, is a powerful method for measuring and reducing a building's environmental impacts. Its widespread adoption among designers would allow the environmental component of sustainability to gain more traction in design philosophy and client goals. Currently, the stakeholders in building design-both design professionals and clients-have few resources for proper LCA education and use, and there are no common metrics agreed upon for reporting the results of LCAs for buildings. This thesis assesses the strengths and weaknesses of resources available to design practitioners for performing LCA, including a pilot credit in the United States Green Building Council's Leadership in Energy and Environmental Design ratings system. A case study performs an LCA comparing two structural materials in an office building. The study aims to be as transparent and repeatable as possible, in order to set a good example on which to model future building LCAs. Based on the critical review of LCA resources and the lessons learned from the case study, eight key points are proposed for improving the quality and transparency of building life cycle assessment projects.

Current structural design practice is primarily concerned with optimizing the construction cost and schedule of a building project, while ensuring that the structure meets basic safety and serviceability requirements. The maintenance costs, alteration/replacement costs, and end-of-life costs associated with the support of the structure after the initial construction process is given far less consideration. Initial research indicates that, for a typical building, the majority of the cost over the system life cycle is incurred after the original structure has been completed. The ultimate value and longevity of a building is, therefore, largely dependant on the ability of the structure to be economically maintained and easily modified during its service life. The objective of this paper is to outline a design process that considers how buildings interact with time. The process involves two fundamental steps: (1) the modularization of the structure to accommodate how different parts of the building change over time and (2) the design of modular components in consideration of their expected service life. Life cycle cost methods are applied to evaluate the performance of design alternatives-thus making it easier to explicitly consider the cost associated with how a structure will be supported and may be adapted over time, in addition to the customary tasks of calculating construction costs and schedules. Despite the apparent benefits to this approach, there are a number of obstacles preventing the adoption of life cycle design principles into professional practice. Specific obstacles to implementation are discussed with respect to the construction industries in both the United States and Japan. The paper concludes with the description of further case study research to be conducted in the Japan during the summer of 2003, the findings of which will be published as an addendum to this document.

Повний текст джерелаBIM (Building Information Modelling) och LCA (Life Cycle Assessment) ligger i kärnan av byggprojekt. LCA är ett nyckelverktyg för hållbarhetsarbete i byggbranschen och en förbättrad LCA-process kan uppnås i och med att tillämpa BIM-verktyg. BIM bjuder på många nyttor däremot detta arbete fokuserar på nyttan som BIM kan ge till LCA-processen. Därmed är forskning på grunden till Bim-baserad LCA-process och datas integrations- och konverteringsförmågan ytterst viktiga för detta arbete. LCA-verktyg One Click LCA och Tally och dess tillägg till CAD-mjukvaror har utvalts för att jämföra resultat vars indata är baserat på olika EPD-databaser (Environmental Product Declaration). För att iaktta skillnader i LCA-resultat, har LCA-processen gjorts med dessa LCA-verkytg. Indata, systemgränser och LCA-definitionsområde var samma för båda LCA-processer. LCA-resultat producerat av båda LCA-verktyg har jämförts utifrån klimatavtrycksperspektiv (Global Warming Potential) för materialframtagandesskede. One Click LCAs GWP-värden har importerats i en Solibri-modell för projektet. Slutligen har LCA-resultat av en Bim-baserad process jämförts med resultat av en klassisk LCA process. Påverkan av geografiskt anpassade EPD-databaser är avgörande för LCA-resultat. Materialframtagandesskede har störst miljöpåverkan i förhållande till andra livsskede. Semantisk detaljnivå av Solibri-modellen är avgörande för identifiering av för- och nackdelar av datas integrations- och konverteringsförmågan. Datainteraktionstyper studerade i BIM-baserade LCA-processer klassas som kollaborativ interaktionstyp. Integrations- och konverteringsförmåga av både BIM-baserade LCA-processer utvärderades på en hög nivå gällande förbättrade resultat, effektivitet och resultatkännslighet. Utöver dessa har BIM-baserade LCA-processer en förbättrad användbarhet och är mer tid- och resurseffektiva, vilka är huvudskillnader från en LCA-process utfört på klassiskt sätt.
